Broadcast channels with confidential messages
Absrfucr-Given two discrete memoryless channels @MC’s) with a common input, it is desired to transmit private messagea to receiver 1 at r&R, andcommon meswgea to both receivers at rate R,, while keeping receiver 2 as ignorant of tbe private messages as possible. Measurhg ignorance by equivocation, a single-letter characterization is given of the. achievable trfplea (RI&R,-,) where 4 is the equi...
متن کاملDiscrete Memoryless Interference and Broadcast Channels with Confidential Messages
Discrete memoryless interference and broadcast channels in which independent confidential messages are sent to two receivers are considered. Confidential messages are transmitted to each receiver with perfect secrecy, as measured by the equivocation at the other receiver. In this paper, we derive inner and outer bounds for the achievable rate regions for these two communication systems.
متن کاملCapacity Results for Relay Channels with Confidential Messages
We consider a communication system where a relay helps transmission of messages from a sender to a receiver. The relay is considered not only as a helper but as a wire-tapper who can obtain some knowledge about transmitted messages. In this paper we study a relay channel with confidential messages(RCC), where a sender attempts to transmit common information to both a receiver and a relay and al...
متن کاملRelay Channels with Confidential Messages
We consider a relay channel where a relay helps the transmission of messages from one sender to one receiver. The relay is considered not only as a sender that helps the message transmission but as a wire-tapper who can obtain some knowledge about the transmitted messages. In this paper we study the coding problem of the relay channel under the situation that some of transmitted messages are co...
متن کاملStrong security and separated code constructions for the broadcast channels with confidential messages
We show that the capacity region of the broadcast channel with confidential messages does not change when the strong security criterion is adopted instead of the weak security criterion traditionally used. We also show a construction method of coding for the broadcast channel with confidential messages by using an arbitrary given coding for the broadcast channel with degraded message sets.
